Hi, how boring: I simply plugged it in and all ports appeared in aconnect. OK, OK, I have installed all necessary software one day before ;-) . Anyway: That's really cool. Thanks to all developers, especially the ALSA team, Takashi Iwai for the famous snd-usb-driver and of course Clemens Ladisch for his work on loading the firmware making usage of midisports a joy. Thanks! One question: The midisport 8x8 can be used as a programmable patchbay in offline use. I used the windows driver panel to set it as desired. But of course I'd like to do this using Linux. In ALSA, there appeared two additional control ports. Are there any sysex commands which can be used to set up the midisport 8x8 patchbay? Best regards ce
